This could also describe the ethos at Green & Tonic in Greenwich, where the food is indeed "mostly plants."

A few years ago, Jeffrey and Cai Pandolfino, former owners of Plum in Cos Cob, switched from serving comfort food to a more health-conscious menu when they started Green & Tonic, a purveyor of plant-based food.

Now, they've opened another location on Railroad Avenue in Greenwich, an easy spot to draw both commuters and the post-workout crowd.

His wife, Cai, a co-owner at Green & Tonic, joined the business in February, after leaving a position at Le Pain Quotidien.

"We want people to feel better," Jeffrey Pandolfino said. "Food should be like medicine. I've really spent the last four or five years focusing on exercise and eating the right kind of foods. It's been a fun ride so far. I think there was a huge need for this in Greenwich."

Green & Tonic started with two locations in Darien and Cos Cob in 2012, and on Railroad Avenue, a quick walk from the train station and nearby fitness studios, Pandolfino said he's found an ideal location.

The interior of Green & Tonic, painted in eye-catching lime green and white, boasts a profusion of hanging plants, suggesting green foods take center stage. The shop employs about 10 people, some trained at the Center for Integrative Nutrition.

The clientele "ranges from the Greenwich mom popping in to the hedge fund guy or girl stopping by for a smoothie when they may have had an ice cream cone before," Pandolfino said.

Green & Tonic hopes to engage the community in discussions about health with plans to start hosting "healthy happy hour" this summer, bringing in health professionals to address topics like nutrition, energy healing and massage therapy.

"Their offerings are what a lot people want to employ in their daily lifestyle, but do you see yourself juicing your own beets and kale? No! Eating healthy requires effort, discipline and often time, of which we all need help with," she said.
